SharpnessDIN45692

class ansys.sound.core.psychoacoustics.SharpnessDIN45692(signal=None, field_type='Free')

Computes the sharpness of a signal according to the DIN 45692 standard.

Note

The calculation of this indicator is based on the specific loudness result from the loudness model for stationary sounds defined in the ISO 532-1 standard. This is the same loudness model used in the LoudnessISO532_1_Stationary class.

Class instantiation takes the following parameters.

Parameters:

signalField, default: None

Signal in Pa on which to compute sharpness.

field_typestr, default: “Free”

Sound field type. Available options are “Free” and “Diffuse”.
